Between Club Mill Road and the Don, a dense wall of tangled vegetation, hiding what? The Secret Garden? Sleeping Beauty& #39;s castle? @WardsendCem #Sheffield @UpperDonTrail

1947 image from Britain from Above. That line in the landscape marks the nearest straight side of the square footing for the nearest cooling tower (still with its wartime camouflage paint). So within there may be...concrete, debris, danger, and nature showing its own power

Zooming in on the same image. the corner nearest the river...

...and that corner in the brambles on Sunday

The same corner 18 months ago (but it feels like 3 or 4 years).

Concrete footing to the left, substation to the right, Club Mill Road with its high wall at the back
